Search reaction times as a function of set size for complex searches and their associated simple searches. LNS searches and their associated simple searches are indicated using red lines, and LS searches and their associated simple searches use blue lines. Search times are averaged across conditions in which LNS searches were harder than LS searches (top row, panels A through D) and vice versa (bottom row, panels E through H). The first two simple searches measure target-distracter similarity (panels B and F for TD1; C and G for TD2, middle panels), and the last simple search (panels D and H) measures distracter-distracter similarity or distracter homogeneity (D1D2). The green asterisk in each panel denotes a statistically significant main effect (p < 0.0001) of search configuration (LS vs. LNS) (see text).
